UNITED STATES EETCE0 PATENT CHARLES BAGLEY, OF MECHANICSVILLE, IOWYA.

SPECIFICATION forming part of Letters Patent No. 400,428, dated April 2 1889. Application led May 7, 1888. `Serial No. 273,142. (No model.)

To a/ZZ whom t 17a/ay concern:

Be it known that I, CHARLES BAGLEY, a citizen of the United 'States of America, residing at Mechanicsville, in the county of Cedar and State of Iowa, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in pumps of that class which are provided with a hollow piston-rod and valves so organized that the water lifted by the hollowv valved piston -rod is drawn through and above the lower valve and through the valved piston and forced out of the hollow section of the piston-rod, water also being admitted through a valved opening in the cylinder above the movement of the piston, so that water is raised on both the up and down stroke of the piston-rod to provide a continuous flow; and it consists in the construction, combination, and arrangement of `the parts, as will be herein after fully set forth,

and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional view taken through the piston or lower portion of a pump constructed in accordance with my invention. Fig. 2 is a sectional view taken through the line m :r of Fig. l, and Fig. 3 is a sectional view taken through the line y Iy of Fig. l.

A and A refer to upper and lower cylinders. A iiat disk, B2, constructed with channels or grooves 77, in its upper and lower faces, is interposed centrally between the two cylinders, and the contiguous end of the latter rests within the grooves thereof. Upper and lower heads, B and B, are also provided and grooved to receive the respective upper and llower ends of the cylinders A and A. The upper' head, B, is formed with peripheral apertures and a central screw-threaded eduction-opening, in which is secured the lower end of the dischargesp'out C. The lower head, B, is also provided with peripheral apertures and with a central valve-opening, C. Below the valve-openin g C the head B is formed with a circular recess, C2, and on the top surface of said head an upwardly-openin g clack-valve, CZ, is secured. Against the lower head, B', a plate,B3, is placed, which is of equal diametric cross-section as said head, and has peripheral apertures therein adapted to align with the similar apertures in the head B. The upper part of the plate B3 is provided with a circular i'ecess, b', of the same dimension as t-he recess C2 in the under part of the head B, and when the said head and plate are placed together, as shown, a circular chamber is formed below the valve-opening C. By the formation of the recess h in the plate B3 the metal at this point is necessarily reduced in thickness, and is provided with a series of apertures, b2, to form a strainer to prevent the entrance into the lower cylinder, A', of large particles of vegetable or other matter. The suction of the water through the valve-opening C would, to a small degree, be retarded by the small perforations h2, and to avoid any intermittent action the chamber is provided between the head B and plate B3, and allows the water to iiow therein and be temporarily stored. The saidcha-mber is somewhat larger than the valve-opening C', and time is thereby allowed to replenish the volume of water in said chamber by the action of the rising piston-'head before it is entirely emptied, and thus make the flow continuous. The disk B2 has a circular recess, 71.', formed in its top face, and extending from the bottom of said recess through the under side of the disk is a series of diametricallyarranged apertures, fi. Inside of ,said apertures t a large central aperture is formed for passage therethrough of the piston-rod.

Loosely mounted in the recess 7L of the disk B2 is a valve-plate, H, also provided with a central opening, through which the pistonrod passes. Adjacent to the periphery of the plate II and diametrically opposite to each other headed rods 7s are attached. These rods.

vcross-scction than the diameter of the open- IOO ings i, and the upward movement of the said plate is limited by the heads of the rods la striking against the under side of the disk B2. Buckling of said plates by the strain thereon is also prevented by said rods, for the reason that the rods are of equal length and are attached to the plate at four points adjacent to its periphery.

lVhen the two heads B and i', disks B2, and lower plate, @3, are mounted as set forth, headed rods b are passed through the peripheral apertures in the plate B2 and head B', up through similar apertures in the disk B2, and then through like apertures in the head B, and nuts applied to the upper screwthreaded ends thereof on top of the latter head, and the parts thereby secured and clamped together. The rods l), passing through the disk 32, support the said disk and two cylinders in alignment at all times. If such construction were not provided, an yslight jar or shock would sag the cylinders A and A', owing to their length, at the point where they engage with the disk B2, and cramp the plate l'I and the piston-rod to such an extent as to seriously injure the operation of the pump. I employ a hollow piston-rod, F., to the upper open end of which a solid piston-rod, E', is secured by a yoke, e, formed on the lower end of the rod E'. The hollow rod or pipe E passes through the central openings of the plate ll and disk B2 and extends downward into the lower cylinder, A'. The lower end of the pipeE is provided with two sets of screwthreads, c' and e2, separated by a blank space, e2. The lowermost end of the said pipe E is sccured in a central screw-threaded aperture of a piston-head, F. Before thelower end of the pipe E is attached to the piston-head F it is passed through a central aperture in a dished packing, F', and a screw-threaded washer, j". Then the lower end of the pipe or hollow piston E has been secured in the piston-head F, the under side of the packing F' will rest ou the top surface of the piston-head, and the washer j" will be secured down against the packing, engaging with the screw-threaded surface c and the periphery of the aperture of the packing F' with the blank space c2 on the lower end of the piston or pipe E.

The piston-head F is substantially rectangular in cross-section and has a chamber, f, formed therein, with which the pipe E directly communicates. The lower end of the pistonhcad F is also formed with a central screwthreaded aperture, in which is secured a valveseat, G, having shoulders g2 formed therewith, and provided with a cup-shaped depression with a central aperture.

Between the shoulders g2 andthe lower end of the piston-head a packing, F2, similar in shape to the packing F', is secured in a reverse position to the packing F'. A gravityvalve, g, having a suitable packing, is placed in the chamber f and normally bears on the top surface of the seat G. rlhis valve g has a rod, g', centrally attached thereto, which passes through the central aperture in the seat G and limits the upward movement of said valve and has a tendency to properly guide it back to its seat.

The packings F and F2 are of suitable cxpansible material and bear against the inner surface of the lower cylinder, A', andthcy are the only parts of the piston-head which touch the said cylinder, thereby avoiding unnecessary friction and at the same time providing a water and air tight attacln'nent at each end of the said head.

In mounting my improved pump it will bc understood that the lower cylinder, A', is entirely submerged and a whole or a part of the upper cylinder, A. In starting the operation of the pump, the pistonhcad or plunger F is raised, which opens the valve (l in thc lower end of the cylinder A' and draws a quantity of water into the said cylinder below the piston head or plunger. 0n the downstroke of the plunger the valve f/ is raised and water flows into the cylinder f of the plunger and is forced up through tne hollow piston rod or pipeE by successive desccnsions of the said plunger. Water can have ingress into the pipe solely through the valve g in the bottom of the plunger F. On the downstroke of the plunger F the valve d is drawn inward and water freely liows into the lower cylinder, A', through the opening D, and the water enters the cylinder A above the plunger F. On the upstroke of the plunger the valve d' is closed and the water above the same is lifted and forced through the openings in the disk B2, the valve H rising from its seat and allowing the water to enter the cylinder A.

3y the successive operations above set forth the cylinder A eventually becomes-filled by the water overliowin g from the top of the pipe E and that passing through the disk-plate B2, and is forced out through the spout branch C. The Valve Il descends at each downstrokc of the plunger, being forced down to its scat by the suction produced by the descent of the plunger and raised therefrom by the force of the water elevated by the upstroke of the plunger. \Vhen the valve H is thus drawn down closely to its seat, a distinct and tight chamber is formed between the upper end of the plunger F and the lower side of the disk B2. The suction caused by the descent of the plunger is thereby brought to bear on the inner surface of the chamber thus formed, and the .valve d' is affected thereby and responds thereto by opening inward and allowing water to flow into the cylinder A' above the plunger F. The dished packings F' and F2, as hereinbefore set forth, are the only parts of the plunger F which Contact with the inner surface of the cylinder A'. These packings expand and bear iirmly against the said cylinder A', and while a perfect water-tight construction is provided the friction is materially reduced and the operation of thc plunger rendercd easy. All the water elevated by the forcing action of the pump must necessarily IOO IlO

pass through the valved opening in the lower en d of the plunger and up through the pipeV E, overflowing therefrom into the upper cylinder, A. All the water that is elevated by the lifting action of thepump is drawn into the lower cylinder, A', through the valved opening D therein7 as hereinbefore set forth, and forced up through the apertures in the disk B2 around the valve II into the cylinder A. Thus it will be seen that the forcing and lifting actions of the pump about counterbalance each other, and that about an equal quantity of water is elevated by both. The volu me of water running into the cylinder A by the overflow from the upper open end of the pipe E is of itself elevated by the lifted volume of water passing through the apertures in the disk-plate B2. By this means a double force is brought into play to fill the cylinder A and cause a steady unintermittent iiow from the spout branch C, and to unceasingly sustain such filling and flow without the use of compression or air chambers or supplementary branch cylinders or pipes.

Having thus described my invention, what I claim as new is- U 1. In a double-acting pump, the combinaftion, substantially as set forth, of a sectional cylinder having heads with a central and peripheral apertures, and the one face of each provided with a channel or groove fit-ting, re- A spectively, over the upper and lower ends of the upper and lower sections of said cylinder, the head of the lower section having a central valved opening and the upper part of one side of said' section provided with a similar opening, a central disk or flat plate provided with grooves or channels in both faces thereof fitting over and unitedly supporting the contiguous ends of the sections of the cylinders,. having a valve-recess in its upper face, with a central piston-opening surrounded by valve-openings extending through the bottom of said recess and outer peripheral apertures,l a hollow piston-rod or pipe having an open top connected at itsupper end to a solid piston-rod, a chambered piston head or plunger attached to and in direct coinmunication with the lower end of the hollow in connection with and passing through the l peripheral apertures in the heads of the cylinders and through the peripheral apertures in the centrally-interposed disk-pla`te on the outside of the cylindrical sections.

2. In a double-acting pump, the combination ,with the sectional cylinder, of the grooved or channeled heads projecting outwardly beyond said sections to provide iianges in which peripheral apertures are formed, the single central valve-disk or hat plate having grooves or channels therein inside of the periphery thereof for the reception andsupport of the contiguous ends of the cylinder-sections, and by` the inner formation of the grooves or channels providing iianges projecting outwardly beyond the circumference of the said cylinders and having peripheral apertures therein, and the elongated tie-rods held in connection with the upper and lower heads of the cylinders and freely passing through the peripheral apertures in the central disk or plate to secure said heads upon the ends of the cylinders and hold the cylinder-sections in rigid alignment by passing through the disk-plates, substantially as described.

, 3. In a double-acting pump, the combination, with the lower cylindrical section, of a Aformed therein, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
